Christopher Barry is most certainly not a troll.

As shown in the LKML and Debian debates, the systemd infestation was firmly opposed by nearly everyone outside the 'vested interest' RedHat filter bubble. And still is.

Some high profile names would be Eric S. Raymond or Patrick Volkerding (creator of Slackware).

Debian has been forked over this; https://en.wikipedia.org/wiki/Devuan

That is not him saying that people should stop developing. It's him saying stop this behaviour.

It's him finally calling Kay Sievers out for being incompetent and an asshole. Which was long overdue.

Sadly it's by far too late and will very likely not change a thing about systemd's "break and extinguish" strategy.

Systemd will continue to break other peoples projects in its effort to replace every mature service implementation with a hacked up systemd imitation.

At least until, hopefully, the major distros finally acknowledge their mistake and roll this disaster back.
